This BrainBashers safe has a rather unusual control panel.
In order to open the safe, you have to press every single button once only, in the correct sequence, ending on the button marked E.
Each button indicates which button to press next, for example, 2U means move up 2 buttons and 3R means move right 3 buttons.
Can you determine which button you must start with?
4R | 4D | 1R | 1D | 2D | 4L | 1D |
1R | 4D | 5D | 2R | 2D | 1L | 4L |
2R | 1D | 1L | 2R | 2R | 2D | 2U |

Puzzle 4
Imagine a bottle recycling skip, empty other than one lonely bottle.
Every hour, on the hour, people come and put bottles into the skip.
The first hour, at noon, one person came and put a bottle in.
One hour later, two people each placed a bottle into the skip.
An hour later, four people each placed a bottle into the skip.
This doubling of people continued until 11pm, when the skip was finally full.
When was the skip exactly half full?
